Gsmtool Is Online

Nov 21st, 2012

After mac2vendor another old tool that I
made is back online on the new site.
Gsmtool is back new and improved.
This tool lets you lookup which operator a GSM IMSI number belongs
to or list all the Mobile Network Codes for a certain Mobile Country Code.

The old version was based on information from Wikipedia, this new
version uses information from the ITU and should therefore be a lot
more accurate. Also, the previous version did not handle 3 digit MNC
codes properly.

Also: Really, ITU, who on earth shares long lists of assignments in
MS Word format?!
But that aside… Luckily vi and awk are here to save the day.
